Ultrastructure of the larval midgut of Bittacus planus (Mecoptera: Bittacidae) and Neopanorpa longiprocessa (Mecoptera: Panorpidae)

Tissue and Cell, 2017
Bittacidae and Panorpidae are the two largest families in Mecoptera. The larvae of Bittacidae are different from those of Panorpidae in external morphology and habits, and have an interesting habit of spraying the body surface with soil through the anus.

Evolution and mandibular sexual dimorphism in mid‐Cretaceous scorpionflies (Insecta: Mecoptera: Meropeidae)

Journal of Systematics and Evolution
Based on several earwigfly specimens with well‐preserved mouthparts of Meropeidae from mid‐Cretaceous Burmese amber, a detailed, initial analysis was conducted of the structure of Mesozoic meropeids.

Taxonomy of the Panorpa semifasciata group (Mecoptera: Panorpidae: Panorpinae), with descriptions of fourteen new species from China

Annales de la Societe Entomologique de France
Summary Previously, the Panorpa semifasciata group sensu Wang & Hua, 2021 comprised four known species that are endemic to Southwestern China. In this paper, I illustrate and describe 14 new species, increasing the species number of this group to 18. The

Mecoptera is paraphyletic: multiple genes and phylogeny of Mecoptera and Siphonaptera

Zoologica Scripta, 2002
Phylogenetic relationships among members of the Mecoptera and Siphonaptera were inferred from DNA sequence data. Four loci (18S and 28S ribosomal DNA, cytochrome oxidase II and elongation factor‐1α) were sequenced for 69 taxa selected to represent major flea and mecopteran lineages.

Wing-hearts in Mecoptera (insecta)

International Journal of Insect Morphology and Embryology, 1993
Abstract The accessory pulsatile organs for hemolymph circulation in the wings of 7 Mecoptera species were investigated by means of serial semi-thin sections, SEM and TEM. The wing-hearts are located in the dorsal meso- and metathorax, and have no connection to the aorta.
